ListView的使用

把属性View设置为Details，确保列可以显示出来

   this.listView1.View = System.Windows.Forms.View.Details;

属性Columns根据需要添加

   this.listView1.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] {
            this.columnHeader1,
            this.columnHeader2});

  this.columnHeader1 = ((System.Windows.Forms.ColumnHeader)(new System.Windows.Forms.ColumnHeader()));
            this.columnHeader1.Text = "客户端地址";
            this.columnHeader1.Width = 200;

 this.columnHeader2 = ((System.Windows.Forms.ColumnHeader)(new System.Windows.Forms.ColumnHeader()));
            this.columnHeader2.Text = "上线时间";
            this.columnHeader2.Width = 200;

添加

ListViewItem listViewItem = new ListViewItem(new[]
            {
                e.IpEndPoint.ToString(),
                e.DateTime.ToString("yyyy-MM-dd HH:mm:ss.fff")
            }) {Name = e.Id.ToString()};
            listView1.Invoke((MethodInvoker)delegate
            {
                listView1.Items.Add(listViewItem);
            });

移除

   string name = e.Id.ToString();

            listView1.Invoke((MethodInvoker) delegate
            {
                if (listView1.Items.ContainsKey(name))
                {
                    listView1.Items.RemoveByKey(name);
                }
            });
